Abstract

A device for coating planar workpieces with free-flowing materials has an application roller (11) and a mating roller, between which the workpiece is inserted, as well as a metering roller (10) which is arranged parallel to the application roller (11) and can be pressed against it. In this case, the metering roller (10) is arranged in a swinging element (15) so as to be capable of pivoting about a horizontal axis perpendicular to the direction of the adjustment stroke, the swinging element (15) itself being pivotably seated in a horizontally displaceable, lockable bearing block (14). A pneumatic or hydraulic cylinder (16) which acts on the swinging element (15) in order to set the adjustment stroke and thus the contact pressure between the application roller (11) and metering roller (10) is permanently arranged in this bearing block. With this arrangement, frictional effects are reduced to a minimum and extremely precise control of the application gap, in particular even with low contact forces, is thus made possible. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zur Be­schichtung planer Werkstücke mit fließfähigen Werkstoffen gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for coating flat workpieces with flowable materials according to the preamble of claim 1.

Eine solche Vorrichtung ist aus der DE-PS 34 29 049 bekannt. Bei dieser vorbekannten Vorrichtung ist je­weils ein Hydraulikzylinder koaxial zur Gewindespindel angeordnet, so daß die Gewindespindeln über ein Hydraulikpolster mittelbar auf die verschiebbaren La­gerblöcke der Dosierwalze einwirken. Die Einstellung des Auftragsspaltes zwischen Dosierwalze und Auftrags­walze erfolgt bei dieser vorbekannten Vorrichtung daher durch horizontale Verschiebung der Lagerblöcke der Dosierwalze. Die hiermit zwangsläufig verbundene Gleitreibung beeinflußt zwangsläufig die Steuerung des Auftragsspaltes zwischen Dosierwalze und Auftragswalze insbesondere bei geringen Andruckkräften und führt somit zu Ungenauigkeiten.Such a device is known from DE-PS 34 29 049. In this known device, a hydraulic cylinder is arranged coaxially to the threaded spindle, so that the threaded spindles act indirectly on the movable bearing blocks of the metering roller via a hydraulic cushion. The setting of the application gap between the metering roller and application roller is therefore carried out in this known device by horizontal displacement of the bearing blocks of the metering roller. The sliding friction inevitably associated with this inevitably influences the control of the application gap between the metering roller and application roller, in particular with low pressure forces, and thus leads to inaccuracies.

Aufgabe der Erfindung ist es daher, die vorbekannte Vorrichtung so zu verbessern, daß derartige Reibungs­effekte auf ein Minimum reduziert werden und somit eine präzisere Steuerung des Auftragspaltes insbeson­dere bei geringen Andruckkräften möglich wird.The object of the invention is therefore to improve the known device so that such friction effects are reduced to a minimum and thus a more precise control of the application gap is possible, especially with low pressure forces.

Erfindungsgemäß wird diese Aufgabe gemäß dem kenn­zeichnenden Teil des Patentanspruchs 1 gelöst.According to the invention, this object is achieved in accordance with the characterizing part of patent claim 1.

Der Erfindungsgedanke besteht also im wesentlichen darin, daß der horizontal verschiebbare Lagerblock mit dem integrierten Pneumatikzylinder über die Gewinde­stange nur noch zur Grobeinstellung insofern eingesetzt wird, als hierdurch ein Maximal-­Auftragsspalt zwischen Auftrags- und Dosierwalze ein­stellbar wird, die den Verschiebeweg des Lagerblockes begrenzen. Dagegen erfolgt die eigentliche Feinein­stellung des Auftragsspaltes über das im Lagerblock schwenkbar gehaltene Pendelglied, an dem der Pneumatik-Zylinder angreift und in dem die Dosierwalze gelagert ist. Der Einstellung des Auftragsspaltes führende Dosierhub des Pneumatikzylinders im Bereich von einigen Millimetern führt somit zu einer minimalen Verschwenkung des Pendelgliedes und damit zu einer minimalen Lagerreibung in der Drehachse X-X des Pendelgliedes, die durch Einsatz geeigneter technischer Mittel (z.B. Nadellagerung) noch weiter minimiert werden kann, so daß der Dosierhub praktisch reibungsfrei erfolgen kann, im Gegensatz zum wesentlich höheren Haft-Gleitreibungseffekt der Lagerblöcke bei der vorbekannten Vorrichtung.The idea of the invention essentially consists in the fact that the horizontally displaceable bearing block with the integrated pneumatic cylinder is only used for the rough adjustment via the threaded rod insofar as a maximum order gap between the application and metering roller can thereby be set, which limit the displacement path of the bearing block. In contrast, the actual fine adjustment of the application gap takes place via the pendulum member which is pivotally held in the bearing block and on which the pneumatic cylinder acts and in which the metering roller is mounted. The setting of the dosing stroke of the pneumatic cylinder leading to the application gap in the range of a few millimeters thus leads to a minimal pivoting of the pendulum member and thus to a minimal bearing friction in the axis of rotation XX of the pendulum member, which can be further minimized by using suitable technical means (eg needle bearing). so that the metering stroke can take place practically without friction, in contrast to the much higher static sliding friction effect of the bearing blocks in the previously known device.

Dies bedeutet, daß auch bei sehr empfindlichen Steuerungen des Auftragsspaltes Reibungseffekte die Einstellgenauigkeit des Auftragsspaltes bzw. des Dosierhubes praktisch nicht mehr beeinflussen.This means that even with very sensitive controls of the application gap, friction effects practically no longer influence the setting accuracy of the application gap or the metering stroke.

Gemäß einer weiteren Ausgestaltung gemäß dem Patentan­spruch 2 wird ein möglicher Gleitreibungseffekt zwischen der Stirnseite des Pneumatikkolbens einerseits und der zugehörigen Angriffsfläche des Pen­delgliedes andererseits durch ein Nadellager ebenfalls praktisch ausgeschlossen.According to a further embodiment according to claim 2, a possible sliding friction effect between the end face of the pneumatic piston on the one hand and the associated contact surface of the pendulum member on the other hand is also practically excluded by a needle bearing.

Zur vollen Ausnutzung der feinfühligen mechanischen Einstellung des Auftragsspaltes durch die erfindungs­gemäßen Maßnahmen ist weiterhin noch vorgesehen, daß die beiden Pneumatikzylinder von einem gemeinsamen Proportional-Druckregelventil angesteuert werden, so daß auch von der steuerungstechnischen Seite eine hohe Einstellpräzision und Reproduzierbarkeit der Einstellung möglich wird, das Proportional-­Druckregelventil bildet demnach die sinngemäße und vorteilhafte Ergänzung einer sensiblen Steuerung des Auftragsspaltes von der steuerungstechnischen Seite her.To take full advantage of the sensitive mechanical setting of the application gap by the measures according to the invention, it is also provided that the two pneumatic cylinders are controlled by a common proportional pressure control valve, so that a high setting precision and reproducibility of the setting is also possible from the control side, the proportional Pressure control valve accordingly forms the appropriate and advantageous addition to a sensitive control of the order gap from the control side.

Ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung wird nun anhand von Zeichnungen näher erläutert, es zeigen:

  • Figur 1: Eine schematische perspektivische Darstellung der gesamten Vorrichtung, und
  • Figur 2: eine Seitenansicht des Pendelgliedes gemäß Figur 1.
An embodiment of the device according to the invention will now be explained in more detail with reference to drawings, in which:
  • Figure 1: A schematic perspective view of the entire device, and
  • FIG. 2: a side view of the pendulum member according to FIG. 1.

Die in Figur 1 dargstellte Vorrichtung zum Beschichten von planen Werkstücken besteht aus einer Auftragswal­ze 11 und einer parallel hierzu liegenden Dosierwalze 10, die linienförmig an die Auftragswalze 11 anpreßbar ist, wobei die Breite des zwischen diesen beiden Walzen sich bildenden Walzenspaltes durch Verschiebung der Dosierwalze in Richtung der Auftragswalze einjusiterbar ist.The device for coating flat workpieces shown in FIG. 1 consists of an application roller 11 and a metering roller 10 lying parallel thereto, which can be pressed linearly against the application roller 11, the width of the nip formed between these two rollers being displaced in the direction of the application roller can be adjusted.

Zur Einstellung des Auftragsspaltes, d.h. zur Erzeugung eines geeigneten Dosierhubes, sind folgende Einrichtungen vorgesehen, wobei in Figur 1 nur die entsprechenden Einrichtungen der rechten Seite mit Bezugszeichen versehen sind, grundsätzlich ist die linke Seite der Vorrichtung identisch aufgebaut:To set the order gap, i.e. The following devices are provided for generating a suitable dosing stroke, only the corresponding devices on the right-hand side being provided with reference numerals in FIG.

Die Welle 10A der Dosierwalze 10 (Drehachse Y-Y) ist beidseitig in einem Pendelglied 15 gelagert, das gabelartig vom hinteren Ende eines Lagerblocks 14 um­schlossen wird und dort verschwenkbar (Achse X-X) gehalten ist, wobei die beiden Achsen X-X und Y-Y je­weils horizontal und parallel zueinander liegen und die Drehachse Y-Y der Dosierwalze 10 unterhalb der Drehachse X-X des Pendelgliedes 15 zu liegen kommt.The shaft 10A of the metering roller 10 (axis of rotation YY) mounted on both sides in a pendulum member 15, which is enclosed in a fork-like manner by the rear end of a bearing block 14 and is pivotably held there (axis XX), the two axes XX and YY each lying horizontally and parallel to one another and the axis of rotation YY of the metering roller 10 below the axis of rotation XX of the pendulum member 15 comes to rest.

Der Lagerblock 14 ist an seiner Vorderseite fest mit einer Gewindestange 12 verbunden, die über Konter­muttern 12A,12B an einer ortsfesten Traverse 13 fest­setzbar ist, so daß durch Einjustierung der Gewinde­stange 12 mittels der Kontermuttern 12A,12B eine Grab­einstellung des Lagerblockes 14 und damit eines maximalen Auftragsspaltes zwischen den Walzen 10 und 11 erfolgen kann. Wenn diese Grobeinstellung einmal erfolgt ist, verbleibt der Lagerblock 14 daher stationär.The bearing block 14 is fixedly connected on its front side to a threaded rod 12, which can be fixed via a lock nut 12A, 12B to a fixed cross member 13, so that by adjusting the threaded rod 12 by means of the lock nuts 12A, 12B, a digging setting of the bearing block 14 and thus a maximum Order gap between the rollers 10 and 11 can take place. Once this rough adjustment has been made, the bearing block 14 therefore remains stationary.

Im Lagerblock 14 ist ein Pneumatikzylinder 16 integriert, dessen Kolbenstange 16A in einer Nut 15A des Pendelgliedes 15 über ein Nadellager 17 etwa in Höhe der Achse Y-Y der Dosierwalze 10 angreift. Die Betätigung des Pneumatikzylinders 16 und die daraus resultierende horizontale Verschiebung (Doppelpfeil C-­C) der Kolbenstange 16A in Richtung auf das Pendelglied 16 übt somit ein Drehmoment auf letzteres aus und führt zu einer Einstellung des Auftragsspaltes zwischen den beiden Walzen 10 und 11. Die longitudinale Verschiebung der Kolbenstange 16A (Doppelpfeil C-C) führt somit zu einer kreisbogenab­schnittartigen Bewegung (Doppelpfeil B-B) der Welle 10A der Dosierwalze 10 und zu einer Abrollbewegung (Doppelpfeil A-A) des Nadellagers 17, das in der Nut 15A des Pendelgliedes 15 vertikal verschiebbar gelagert und geführt ist.A pneumatic cylinder 16 is integrated in the bearing block 14, the piston rod 16A of which engages in a groove 15A of the pendulum member 15 via a needle bearing 17 approximately at the level of the axis YY of the metering roller 10. The actuation of the pneumatic cylinder 16 and the resulting horizontal displacement (double arrow CC) of the piston rod 16A in the direction of the pendulum member 16 thus exerts a torque on the latter and leads to an adjustment of the application gap between the two rollers 10 and 11. The longitudinal displacement of the Piston rod 16A (double arrow CC) thus leads to a circular segment-like movement (double arrow BB) of the shaft 10A of the metering roller 10 and to a rolling movement (double arrow AA) of the needle bearing 17, which is vertically displaceably mounted and guided in the groove 15A of the pendulum member 15.

Beide Pneumatikzylinder 16 werden von einem gemeinsamen Proportional-Druckregelventil 18 angesteuert, so daß eine beidseitig gleichmäßige Beaufschlagung der Pendelglieder 15 gewährleistet ist.Both pneumatic cylinders 16 are controlled by a common proportional pressure control valve 18, so that a uniform action on the pendulum members 15 is ensured on both sides.

Die praktisch reibungsfreie Einstellung des Auftrags­spaltes einerseits und die elektronisch feinfühlige Regelung der Pneumatikzylinder 16 durch das Proportional-Druckventil 18 andererseits ergeben in ihrem Zusammenwirken ein "Präzisionslager" für die Dosierwalze 10, das auch als Baueinheit zur Nachrüstung bestehender Anlagen vorgesehen werden kann.The practically frictionless adjustment of the application gap on the one hand and the electronically sensitive control of the pneumatic cylinders 16 by the proportional pressure valve 18 on the other hand result in their interaction a "precision bearing" for the metering roller 10, which can also be provided as a unit for retrofitting existing systems.
